For us the diaper belt is key! I bought one from Continuum Family with DS1 and sewed several more myself. Super easy to make with elastic and fleece. I find a belt and prefold much faster than using a cover. Also you can have lots of prefolds without making a big investment. With newborns I go through A LOT of prefolds each day until we get in the EC rhythm because we are changing after each pee or tiny bit of poo.
